Overview
The Sontek FlowTracker2 ADV probe can be used in the field with the handheld display, or it can be used in the lab with direct PC connection. The ADV’s acoustic probe and processing electronics are housed in one small, lightweight, easily maneuverable unit, and the acoustic head has an optional, integrated pressure (depth) sensor.
Mechanics
Depth data are even correctable for dynamic pressure (Bernoulli) and altitude effects using SonTek’s patent-pending method. Setup of the probe and PC software is simple and mistake-proof. Just connect the cables between the probe and a laboratory PC or laptop, check a few settings, and press the “Start Logging” button. Data are output directly to a .CSV file that is immediately ready for use in the project, model, or database as required.

Wildfire Prevention in the Sierra Nevada Region with the Yuba Watershed Institute
Though recent wildfires have sparked new conversations about wildfire management and response, groups like the Yuba Watershed Institute have been monitoring the forests and water resources of the Sierra Nevada region for decades, managing approximately 5,000 acres of land with the Bureau of Land Management (BLM) and about 7,000 acres in private land partnerships. The goal of the Institute is to work with local communities and land agencies to improve watershed and forestry management through informed practices and public outreach. The goals of the Yuba Watershed Institute are three-fold: Improve the ability of fire suppression agencies like the California Department of Forestry and Fire Protection ( CAL FIRE ) and the US Forest Service.

Real-time wave data supports accurate weather prediction, safe and efficient maritime operations, and provides valuable safety and operating condition information for recreation and commercial fishing. Understanding wave dynamics also helps with the design of protective coastal structures like seawalls, breakwaters, and jetties. It also supports better prediction of their impact on sediment transport and coastal geomorphology. Wave data is a key factor in qualifying and designing offshore wind farms and harnessing kinetic energy for electrical generation. It helps with the understanding of ocean-atmosphere interactions and contributes to studies of sea-level rise and climate change impacts.
